Spontaneous Combustion in Open Cut Coal Mines

Spontaneous combustion is a potential source of greenhouse gas emissions from open-cut coal mines. Emissions, however, are very variable across the industry; many mines have no instances of spontaneous combustion and therefore no emissions from this source.

Spontaneous Combustion Description

However in coal mines, coals spoken of as being liable to spontaneous combustion are those coals which will develop to an open fire under specific conditions. Many seams will not reach this point. When spontaneous combustion occurs, there is an initial stage where the temperature is rising but no burning in the normal sense is taking place.

Spontaneous Combustion of Coal QMIHSC 2019

Spontaneous combustion (sponcom) of coal remains a major safety issue for underground coal mining operations. Recent heating incidents in Australia further highlight the need of improving current knowledge and practices of sponcom management to ensure safety and productivity of coal mines extracting coal seams that are prone to spontaneous heating.

Spontaneous Coal Combustion Part 1: A Burning

India has the largest concentration of coal fires, and it is estimated that 80% of those fires started due to spontaneous combustion. Indian coal fires were first documented in coal fields located in Raniganj back in 1865. In addition, mines in Jharia, Jharkhand are famous for their rich coal resources, but records show nearly 70 fires have been burning for over 100 years dating back to 1916.
